Colorado’s Air Quality Control Commission unanimously approved a new Colorado Clean Car rule, which essentially follows California’s “Advanced Clean Cars 2” rule but falls short of setting a 2035 target for 100% EV sales.
Colorado has areas of exceptionally poor air quality, particularly in the Northern Front Range, which is home to Denver and its environs and is the most populous area of the state. While Colorado has not yet adopted the full rule, the CAQCC says it will consider full adoption of California’s ACC2 rule no later than 2029. The new Colorado rule targets 82% new EV sales by 2032, which is in line with California’s target for that year but does not set targets for years beyond 2032.
